The hood fits perfectly with bayonet connection (at the same location as the filter adapter) to the G1X. But why is said in the description that also filters remain with usable, is hitherto not risen me. Then would have to be present on the outer ring of the bayonet connections by a 58 mm-threaded in order to optionally use the lens hood can. But it is not and the pictures of the genuine Canon Gegenlichblende my opinion is also seen no thread. Too bad, or someone has an idea on this?
